RE: Field Weakening Point
With field weakened operation, the torque capability is reduced as the frequency (speed) increases. In comparison to speed, the torque capability drops more rapidly than the drop described by a constant horsepower torque vs. speed curve. However, constant horsepower operation can be maintained up to some point like 150% of base speed or so.
